Abstract
Description
Technical Field
[0001] The utility model relates to medical equipment, in particular to an ultrasonic knife with a steering function. Background Art
[0002] The ultrasonic scalpel is mainly composed of an ultrasonic scalpel head and a handle. Its main function is to emulsify human tissue during surgery to facilitate suction and discharge. The original idea is to generate negative pressure in the corresponding human body by vibrating the end at an ultrasonic frequency. The clamped human tissue cells expand under increasing pressure until they burst, thus emulsifying. Moreover, since the water content of diseased tissue in the human body is higher, the diseased tissue is more likely to be emulsified due to cavitation during the vibration process, while blood vessels, nerves and healthy tissues are not greatly affected. Therefore, ultrasonic scalpels are widely used in surgical operations.
[0003] The existing ultrasonic scalpels have the following problems: 1. The ultrasonic scalpels currently on the market only have the function of emulsifying tissue, and do not have the function of clamping and cutting diseased tissue. In existing surgeries, clamping is achieved by other instruments, which requires medical staff to perform other actions, increasing the burden on medical staff and posing hidden dangers to the surgery; 2. Due to different operating angles during the operation, the clamping end needs to be able to turn during the operation to better clamp, cut and emulsify tissue, but the existing clamping instruments do not have the function of turning. Summary of the invention
[0004] Purpose of the utility model: The purpose of the utility model is to provide an ultrasonic scalpel that can simultaneously clamp diseased tissue and emulsify diseased tissue, and has a steering function at the clamping end.
[0005] Technical solution: The ultrasonic knife with steering function described in the utility model includes an ultrasonic transducer, the front end of which is fixedly provided with a contact rod for contacting human tissue, the front end of which is also articulated with a clamp, and the rear end of which is rotatably connected to a fixed column.
[0006] Furthermore, it also includes a plurality of clamping control ropes, a first rotation control rope and a second rotation control rope, the front end of the clamping control rope is fixedly connected to the clamp; the first rotation control rope and the second rotation control rope are opposite in number, and the first rotation control rope and the second rotation control rope are symmetrically arranged with the ultrasonic transducer as the center, and the front ends of the first rotation control rope and the second rotation control rope are respectively fixedly connected to the sides of the ultrasonic transducer.
[0007] Furthermore, the front end of the clamping control cable passes through the fixing column and the ultrasonic transducer in sequence.
[0008] Furthermore, the rear end of the clamping control rope is fixedly connected to the control clamping wheel, and the side of the control clamping wheel is fixedly provided with a clamping handle for turning.
[0009] Furthermore, it also includes a rotation button, and the rear ends of the first rotation control cable and the second rotation control cable are respectively fixedly connected to two side portions opposite to the rotation button.
[0010] Furthermore, it also includes a hand-held handle, a hollow control compartment is set on the top of the hand-held handle, a control clamping wheel is set in the control compartment, the clamping handle extends out of the control compartment to facilitate finger turning; the rotating button extends out of the control compartment to facilitate finger pressing on the side.
[0011] Furthermore, it also includes a connecting crank, the two ends of which are fixedly connected to the fixed column and the hand handle respectively, and a plurality of pulleys for clamping the control cable, the first rotating control cable and the second rotating control cable are arranged in the connecting crank.
[0012] Beneficial effects: Compared with the prior art, the utility model has the following advantages: the utility model drives the clamping control cable to move by toggling the clamping hand handle, thereby controlling the opening and closing of the clamp, thereby realizing the function of the ultrasonic knife clamping the diseased tissue; by pressing the side of the rotating button, the relative positions of the first rotating control cable and the second rotating control cable slide, thereby pulling the ultrasonic transducer to rotate left or right.
